摘要：
A series of N,N'-mono substituted acyclic thiourea ligands are found to be highly active phosphine-free catalysts for palladium catalyzed Heck reaction of aryl iodides and bromides with olefins. We have achieved high turnover numbers for aryl iodides with olefins (TONS up to 970,000 for the reaction of iodobenzene with styrene). (C) 2014 Elsevier Ltd. All rights reserved.
